Abstract
A process for the preparation of 1,6-dichloro-1,6-dideoxy-β-D-fructofuranosyl-4-chloro-4-deoxy-α-galactopyranoside comprising the steps of (a) reacting sucrose with a tritylating agent; (b) acetylating the tritylated reaction product; (c) detritylating the acetylated reaction product; (d) isomerizing the resulting penta-acetate; (e) chlorinating the isomerized product; and (f) deacetylating the chlorinated reaction product.
